Description

Technical Field

[0001] The utility model relates to the technical field of ship bottom structures, in particular to a ship bottom with a glass fiber reinforced plastic composite structure. Background Art

[0002] Ships, also known as ships, are a means of transportation that sails on the sea or in waters. They are mainly used for cargo transportation, passenger transportation or other specific purposes. Ships are designed in a variety of ways, from small sailboats and fishing boats to huge container ships and cruise ships. They have different structures and functions to adapt to different water environments and mission requirements. The fiberglass composite structure ship bottom refers to a ship bottom structure constructed using glass fiber reinforced plastic as the main material. This structure combines the matrix of synthetic resins (such as epoxy resins and polyester resins) with the reinforcement of glass fibers, and is manufactured through a special lamination or mold molding process.

[0003] During the installation and use of ordinary marine FRP composite structure ship bottoms, roll reduction structures are generally not set on the FRP shell for the overall aesthetics of the ship chassis. However, when a ship is sailing at sea, it is easily affected by the waves and rolls. Without the help of a roll reduction structure, the roll amplitude may increase, reducing the stability and safety of navigation.

[0004] Therefore, in summary, it is urgent to propose a marine fiberglass composite structure ship bottom with a roll reduction structure. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a ship's fiberglass composite structure ship bottom with a roll reduction structure.

[0006] The technical scheme of the utility model is: a ship fiberglass composite structure ship bottom, including a fiberglass shell, a ship plywood, a fiberboard, a fireproof board, a keel frame, an auxiliary frame, a mounting cover and a bilge keel, the ship plywood is embedded in the top of the fiberglass shell, the fiberboard is arranged on the inner wall of the fiberglass shell, the fireproof board is arranged on the inner wall of the fiberboard, the keel frame is symmetrically arranged on the inner wall of the fireproof board, the auxiliary frame is symmetrically arranged between the two sides of the keel frame, and the middle part of the rib frame is connected with the inner bottom of the fireproof board, the mounting cover is arranged on the inner rear side of the fireproof board, and the bilge keels are symmetrically arranged on the two sides of the fiberglass shell.

[0007] As a preferred technical solution of the utility model, the bilge keel is made of metal material, and the bilge keel is in an intermittent symmetrical state as a whole.

[0008] As a preferred technical solution of the utility model, it also includes a roll stabilizer fin and a wave deflector. The roll stabilizer fin is installed inside the installation cover, and the fins at both ends of the roll stabilizer are respectively located on the two outer sides of the fiberglass shell, and the roll stabilizer has a driving part. The wave deflector is symmetrically arranged on the rear side of the fins at both ends of the roll stabilizer.

[0009] As a preferred technical solution of the utility model, the fin stabilizer and the wave deflector are both wing-shaped.

[0010] As a preferred technical solution of the utility model, it also includes a bearing seat, a water tank, a cover plate, a partition and a flow pipe. The bearing seat is arranged on the front side of the fiberglass shell, the water tank is arranged on the top of the bearing seat, the cover plate is embedded in the top of the water tank, the partitions are symmetrically arranged on both sides of the inner side of the water tank, and the flow pipe is through-arranged between the partitions on both sides.

[0011] As a preferred technical solution of the utility model, a cavity is left between the two inner walls of the water tank and the partitions on both sides, and the cavity is a liquid-phase containing cavity.

[0012] Beneficial effects: 1. When the ship is sailing, the bilge keel on the outside of the FRP shell can increase the hydrodynamic damping effect of the ship when rolling, and effectively reduce the lateral shaking of the ship when sailing in the waves;

[0013] 2. When the ship passes through the waves, the fin stabilizer cooperates with the wave-breaking plate by controlling the drive components on the fin stabilizer to use the lift and resistance generated by the water flow to offset the tilting moment of the ship caused by the waves, so as to maintain the overall balance of the ship;

[0014] 3. When a ship passing through wind and waves is in a rolling state, the shaking of the ship will cause the water injected into the cavity to continuously flow back and forth through the flow pipe, which can further achieve the effect of reducing the rolling of the ship in the rolling state.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0022] Embodiment: A ship bottom made of glass fiber reinforced plastic composite structure, such as Figure 1-Figure 4 As shown, it includes a fiberglass shell 1, a ship plywood 111, a fiberboard 112, a fireproof board 113, a keel frame 2, an auxiliary frame 3, a mounting cover 4 and a bilge keel 5. The fiberglass shell 1 has a high strength-to-weight ratio, can effectively resist corrosion and wear in the marine environment, and prolong the service life of the ship base. The front end of the fiberglass shell 1 is streamlined, so that it can cut the water flow more smoothly in the water. Compared with a blunt or square bow, it can significantly reduce the water resistance. A ship plywood 111 is embedded in the top of the fiberglass shell 1, and a fiberboard 112 is arranged on the inner wall of the fiberglass shell 1. The fiberboard 112 can further increase the stability of the structure. Under the joint action of the fiberglass shell 1 and the fiberboard 112, the fiberboard 112 can withstand the load of the ship during navigation and mooring. A fireproof board 113 is arranged on the inner wall of the fiberboard 112, and the fireproof board 113 and the fiberglass shell 1 and the fiberboard 112 are connected. The cooperation of the rib plate 112 significantly improves the safety of the ship. When in a fire area, the fireproof board 113 can effectively block the spread of fire, buy precious escape time for passengers and crew members, and reduce fire losses. The inner wall surface of the fireproof board 113 is symmetrically provided with a keel frame 2, and an auxiliary frame 3 is symmetrically provided between the left and right sides of the keel frame 2. The middle part of the rib frame 3 is connected to the inner bottom of the fireproof board 113. The auxiliary frame 3 and the keel frame 2 together constitute the main frame of the hull, ensuring the strength and stability of the ship. An installation cover 4 is provided on the inner rear side of the fireproof board 113, and bilge keels 5 are symmetrically provided on the left and right sides of the fiberglass shell 1, and the bilge keels 5 are made of metal material. The bilge keels 5 can increase the damping of the ship when it rolls and reduce the degree of rolling. The bilge keels 5 are in an intermittent symmetrical state as a whole, thereby minimizing the additional resistance during navigation without losing stability.

[0023] like Figure 1-Figure 3As shown, it also includes a roll-stabilizing fin 6 and a wave-deflecting plate 7. The roll-stabilizing fin 6 is installed inside the mounting cover 4 through a fixing part, and the fins at the left and right ends of the roll-stabilizing fin 6 are respectively located on the left and right outer sides of the fiberglass shell 1, and the roll-stabilizing fin 6 is equipped with a driving part, which can drive the fins of the roll-stabilizing fin 6 to swing and rotate. The rear sides of the fins at the left and right ends of the roll-stabilizing fin 6 are symmetrically provided with wave-deflecting plates 7, and the whole roll-stabilizing fin 6 and the whole wave-deflecting plate 7 are wing-shaped. The roll-stabilizing fin 6 can change the relative angle with the water flow by rotating, thereby generating a lift perpendicular to the water flow direction, and the generated lift can offset or reduce the roll of the ship caused by waves, making the ship more stable.

[0024] like Figure 4-Figure 5 As shown, it also includes a bearing seat 8, a water tank 9, a cover plate 91, a partition 10 and a flow pipe 11. A bearing seat 8 is arranged on the front side of the fiberglass shell 1, and a water tank 9 is arranged on the top of the bearing seat 8 by screws. A cover plate 91 is embedded in the top of the water tank 9, and the cover plate 91 is detachable. Partitions 10 are symmetrically arranged on the left and right sides of the inner side of the water tank 9, and a flow pipe 11 is arranged through the partitions 10 on the left and right sides. The flow pipe 11 and the space formed in the partition 10 are in communication with each other. A cavity 12 is left between the left and right inner walls of the water tank 9 and the partitions 10 on the left and right sides, and the cavity 12 on the left and right sides is a water accommodating cavity, which can be injected with a certain amount of water. When the ship shakes, the water in the cavity 12 on the left and right sides will continuously roll inside through the flow pipe 11, and the force generated by the rolling of the water can neutralize the force of the ship's shaking, thereby ensuring the stability of the ship during navigation.

[0025] After the present ship bottom is installed and used, when the ship is sailing and passing through waves, the bilge keel 5 on the outside of the fiberglass shell 1 can increase the hydrodynamic damping effect of the ship when rolling, reduce the lateral shaking degree of the ship when sailing in the waves, and maintain the balanced state of the ship's navigation. At the same time, when it is necessary to adjust the balanced state of the hull, the control starts the driving member on the anti-roll fin 6, and the driving member drives the fins of the anti-roll fin 6 to swing and rotate. The fins will drive the wave-breaking plate 7 to rotate synchronously during the swinging process. During the swinging process of the fins, the fins will use the lift and resistance generated by the water flow on the anti-roll fin 6 to offset the tilting moment of the ship caused by the waves, thereby enhancing the overall balance of the ship. When the ship is in a rolling state caused by the fluctuations of the waves, the shaking ship will cause the water injected into the cavity 12 to continuously flow back and forth through the circulation pipe 11, and the thrust generated by the flowing water will offset and reduce the overall shaking force of the ship, so that the ship can be anti-rolled when it is in a rolling state.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
